Further develop a website with a Bitrix CMS. New functionalities for the business have to be integrated into the website. Dynamic JavaScript is used for this. The aim is to manage customer requirements for the company's products and services. The company deals in mobile phones and offers all services related to their products. For example, if a customer wants to repair or sell his phone, he can do this quickly and easily in the future using the extended functionality on the website. For example, he can define the device and the date of purchase and the website calculates the price when the device is sold. Repair orders are also triggered via the website. The customer can choose his device type and read out the corresponding defect from a catalog of defects. The customer is shown the price for the repair and the duration of the repair directly on the website. In addition to the repair catalog, price catalogs are also stored because customers can not only sell old devices via the website, but can also buy the devices that have already been sold via the website. All actions can be defined in terms of time.
